Here I compare the Flux Measurements for simulations using the Puchwein+19 UV Background.

For all simulations the box size is 50 Mpc/h and the different computational grids are: \(2048^3\), \(1024^3\) and \(512^3\)

Optical Depth

At higher redshits, the optical depth increases as resolution decreases but it still doesnt look like the one in Puchwein paper ( blue line in figure below )

This is what Onorbe+2017 show for their optical depth resolution analysis:
